Striped Pattern Image Examination Support Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fingerprint and palmprint image examination methods face challenges in accurately matching feature points across images with deformation, poor image quality, and the need for manual counting of ridges, leading to increased examiner burden and errors.
Innovation Solution
A striped pattern image examination support device and method that transforms images to align corresponding charting points, calculates intersecting points, and displays these for easy comparison, reducing the need for manual ridge counting and improving feature point matching accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual ridge counting is used to identify charting points, then feature point matching can be performed, but examiner burden increases and errors occur
Solution Approach 1:
The system automatically performs ridge counting and charting point identification without requiring manual examiner intervention. The automated charting point identification unit counts ridges between feature points and identifies charting points autonomously, eliminating the need for examiners to manually count ridges while maintaining accurate feature point matching.
Solution Approach 2:
The patent replaces the manual mechanical process of ridge counting with an automated image processing system. The automated unit uses computer algorithms to count ridges and identify charting points, substituting the examiner's manual visual inspection and counting process with an automated computational system.
2Reliability
If images are displayed without transformation, then original image quality is preserved, but charting points do not align making comparison difficult
Solution Approach 1:
The system performs image transformation as a preliminary step before display to align charting points. The automated charting point identification unit transforms the images in advance to make corresponding charting points coincide, so that when images are displayed side-by-side, the aligned charting points are already in matching positions for easy comparison.
3Productivity
If automated charting point identification is implemented, then examiner workload is reduced, but accuracy may decrease without proper verification
Solution Approach 1:
The system provides automated verification and validation of charting point identification results. The automated charting point identification unit not only identifies charting points but also verifies the accuracy of ridge counting and charting point identification, providing feedback to ensure the reliability of automated results while maintaining high examiner efficiency.

AI summary
Provided are a striped pattern image examination support device, method, and program. The device includes: image transformation element for transforming at least one of two striped pattern images so as to cause coordinates of charting points, which are points that correspond across the two striped pattern images, to match in a plurality of pairs of the charting points which are included in the two striped pattern images; intersecting point extraction element for calculating coordinates of intersecting points of stripes in the striped pattern images and line segments each of which connects two of the charting points in the striped pattern images; charting diagram display element for displaying the two striped pattern images after transformation by the image transformation element, and displaying figures representing charting points at positions corresponding to coordinates after the transformations of each of the charting points on the two striped pattern images.
